    Hi

    Can anyone recommend someone in Surrey/Sussex area who can strip, clean and balance carbs for a T150T at reasonable cost?

    Thanks in advance,

    Duncan

    Hi Duncan as I live in the N.E I can’t help you directly. But have you considered attending one of the Area Meets, someone there could possibly help.

    Hi Duncan

    To be honest it’s not a hugely complicated process & easily undertaken by someone with patience & a modicum of skill. The easiest part is syncing the slides as it’s done off the bike as they are still attached to the gantry. You need a small drill or rod about 1.5 – 2 mm diameter. Choose 1 slide & make that the datum & adjust the other 2 until the rod just fits under the slide in each carb bore. Snap the throttle open & shut a few times & check after locking off the adjusters that all slides are lifting at the same time & are clearing the throats at the top so you can get full throttle, & the gaps at the bottom are the same by using the rod like a feeler gauge. While the carbs are off the bike blow through all the orifices you can see with compressed air &/or carb cleaner. After refitting the carbs adjust the tickover when warm & pilot airscrews (nominally 2.5 turns out) to achieve a good steady tickover of about 1200 rpm – but not too low as you could suffer low oil pressure. Others may chip in with additional ideas especially if they have nipples fitted in the manifold to accept vacuum gauges, but that’s the way I do it! Good luck if you try it…. Cheers Don.
